Botched KB 3004394 Triggers Error Messages, but No Response From Microsoft
I can report that I’m not having any of the reported issues below on Win 8.1 with the KB installed since yesterday, and all UAC functions work fine.
If yesterday was Black Tuesday, today must be Crash Wednesday.
I’m seeing lots of reports of problems with KB 3004394, which modifies the Windows Root Certificate checker so that it looks for bad root certificates daily. As usual, there’s no confirmation from Microsoft about the problem, no documentation that I can find, and no advice on how to proceed. Users with problems find they go away if they uninstall the patch.
